COMBINED PUMP AND AERATOR.

Application tiled April 13, 1910. Serial No. 555,146.

To all whom it may coiwerm: Be itv known that I, Simair KELLY, a citizen of the United States- :and a resident of Atchison. in the county of Atchison and SIState of Kansas, adminisnratrix of the estate of llonsnr ll'. KELLY, deceased, late a citizen of the United States, andl late resident of Atchison. in the county' of Atchison andV State of Kansas. who didl in his lifetime inlO vent a new and lmproveilk vCombined 'aterlump and Aerator, do declare. that the following is a full, clear, aneil exact description of said invention.

The object of the invent-ion is to provide la new and improved combined water pump and aerator, for use on icisterns, wells and other water supplies and arranged to aerate f the water `whenever the pump is actuated for lifting or raising water.

The invention consists of novel features and parts and combinar-.ions of the saine, which will be more fully described hereinafter and then pointed ont in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification. in which similar characters of reference indicate corresponding parts in both iviews.

Figure l is a sectional side elevation of the improvement, and Fig. i is a sectional plan view of the same on the linie Q--Q of Fig. 1.

A hand-operated water' pump of any approved construction is proavided witlr a cylinder ,t terminating at its imp-per end in a water discharge spout B, andl in the said cylinder A rcciprocates a plunger C connected by the usual plunger rod D :and link E with a hand lever l? under the coaitrol of the operator, for imparting a recipri'icating motion to the plunger C. The plurnger C is provided with the usual valve G :rind a suction valve G is arranged in the bottiioin of the cylinder A. To the' bottom of the cylinder A is secured an air pump cylinder H. by the use of bolts I or similar -itastening devices, and in the said air pump cylinder H reciproeates a piston J provided with upwardly extending rods J passing into the water pump c vlinder A, to be engaged by thic underside of the 'plunger C, so that when tbiie plunger C moves downward it pushes the riods J and conscquently the piston J in ai :downward direc tion. A return movement is given to the piston J when the plunger C is raised, by l 55 'a coil spring K arranged in the lower por- Specification of Letters Patent.

tion of the air pump cylinder H, and pressing with its upper. end against the under side of the piston J and resting with its lower end on the bottom head H of the air pump c vlinder H. To the bottom head H is secured a main suction pipe L extending down into the water of the cistern, well or other water supply, and the upper end of the said main suction pipe-L opens into an extension suction pipe L formed integrally on the head H and extending centrally through the air pump cylinder ll, to connect with the suction valve G in the bottom of the water pump cylinder A. An air discharge pipe X for the air pump cylinder H is attached to the bottom head H and extends downward through the main suction pipe L into the water contained in the cistern, well or other water supply, so that when air is forced through the air pipe N by the action of the piston J in the air pump cylinder Il, then this air passes into the water contained in the cistern, well or other water supply, so as to aerate the Said water. The air pump cylin der ll is provided with a suitable air inlet valve C for admitting air into the said cylinder Il, to be forced outof the same the piston J and through the pipe N into the water for aerating the saine.

The operation is as follows; ll'hen the several parts are in the position illustrated in Fig. 1 and the operator imparts an upward swinging motion to the hand lever F in the direction of the arrow a. then the plunger C is caused to move downward. and in doing so engages the rods J and pushes the same and the piston J downward against the tension of the spring K. The downward movementI of the piston J forces the air contained in the air pump cylinder H down througli the air pipe N into the water, to aerate the same. 'hen the hand lever F is swung down 'ard then the plunger C is raised to draw the water up the suction pipes L, L into the lower end of the water pump c vliiider and to lift the water on top of the plunger C, to discharge the same through the spout B. During this upward movement of the plunger C the piston J is returned b v the action of the previously pressed spring K, air now passing into the air pump cylinder H by way of the air inlet valve C. Now from the foregoing it will be seen that during the down stroke of the plunger C the piston J is actuated to force air into the water contained in the cistern, well or other water supply previous to the water pump lifting water out of the said cistern, well or other water supply. Thus the water is aerated while actuating the water pump.

By arranging the air pump on the lower end of the water pump, as described, and bringing the air pump cylinder H in axial alinementwith the water pump cylinder A, it is evident that an exceedingly simple, strong and durable device is provided, composed of comparatively few parts, not liable easily to get out. of order.

Having thus described the invention, I claim as -new and desire to secure by Letters Patent.:

1. A combined pump and aerator, comprising a water pump and an air pump, the piston of the air pump being separate from the plunger of thel water pump and adaptl by the plunger of the water pump at the ed to be moved in one direction thereby, and means for moving the said piston of the air pump in the opposite direction.

Q. A combined pump and aerator, comprising a hand water pump, having a cylinder provided with a suction pipe, and an air pump having a cylinder at the lower end of the water pump cylinder and in axial alinement therewith, the suction pipe extending through the said air pump cylinder, the piston of the air pump being controlled by the plunger of the water pump.

A combined pump and aerator, coinprising a water pump, and an air pump atthe lower end of the said water pump and in axial alinement therewith, the piston of the air pump being spring-pressed in one directionV and adapted to be moved by the plunger of the said water pump in the opposite direction.

et. A combined pump and aerator, com. prising a water pump having a cylinder. plunger and suction pipe. and an air pump having a cylinder secured to the lower end of the saidwater pump cylinder, a piston in the said air pump cylinder and provided with rods extending upinto the water pump cylinder to be engaged by the said plunger, and a. spring pressing the said piston for returning the latter on the return of the plunger.

5. A combined pump and aerator, comprising a water cylinder having a suction pipe, a plunger reciprocating in the said cylinder, an air cylinder below the water cylinder and through which extends the said suction pipe, an air discharge pipe leading from the said air cylinder, and a springpresscd piston in the said air cylinder and moved against the tension of its spring by the said plunger. A

6. A vcombined pump and aerator, comprising a water pump having a cylinder, plunger and suction pipe, and an air pump having a cylinder secured to the lower end of the said water pump cylinder and through which extends centrally the said suction pipe, a piston in the said air pump `cylinder and provided with rods extending up into the water pump cylinder to be engaged by the said plunger, and a spring pressing' Vthe said piston for returning the latter on the return of the plunger, the spring being coiied around the suction pipe.

7. combinei pump and aerator, comprising a water pump and an air pump in axial alinement-- with the said water pump, the piston of the air pump being actuated time the plunger is on the'dowiustroke and the piston is on the compression stroke, and a spring for returning the said piston at the time the plunger ison the lifting or suction stroke. I

S. A combined water pump and aerator, comprising a water pump having a cylinder with a suction valve in its bottom, and a hand actuated plunger reciprocating in the said water pump cylinder, an air pump cylinder fastened to the lower end of the said water pump cylinder and having a central water suction pipe for thesaid suction valve, a piston in the said air pump cylinder slidable on the said suction pipe and provided with rods extending up into the said water pump cylinder to be engaged by the said plunger, a coil spring in the said air pump cylinder for pressing the said piston upward, a main suction pipe extending downward from the lower head of the said air pump cylinder and in register with the said suction pipe, and an air discharge pipe extending downward from the lower head of the said air pump cylinder and passing through the said main suction pipe.
